Check it out I want to help you out this is an RO system from marine depot it’s not an RODI system
I do use rodi but I used to use this one we have ground water here and it’s pretty clean and this RO unit was able to strip the water to 0 TDS I’m sure it will be better than your tap water hands down it uses two carbon blocks one sediment filter in the 75 gallon per day RO membrane and someone on this forum may even be able to help you convert it into a DI system
The membrane and the carbon blocks and sediment filter will definitely need to be replaced and you can get the filter kit from marine depot
It will cost you the shipping that’s it you can pay it forward to someone else in the future
LMK and it’s yours
Oh yeah welcome to R2R
